43991292 divided by 52 
The aim is to understand the frequency of 52 in 43991292.

Let's proceed to step 1:
When dividing 4 by 52, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 52

Let's proceed to step 2:
43 divided by 52 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 52

On to step 3:
If we divide 439 by 52, we get 8 and a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 416 from 439 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 52

Advancing to step 4:
When dividing 239 by 52, we get 4 with a remainder of 31.
The next digit of our result is 4. 
Result so far: 84.0
If we subtract 208 from 239, we get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 52

On to step 5:
The number 52 fits into 311 5 times, leaving a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 845.0
Deduct 260 from 311 and we're left with 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 52

Going ahead to step 6:
The number 52 fits into 512 9 times, leaving a remainder of 44.
The next digit of our result is 9. 
Result so far: 8459.0
Subtract 468 from 512 to get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 52

Moving on to step 7:
52 can be fit into 449 8 times, resulting in a remainder of 33.
The next digit of our result is 8. 
Result so far: 84598.0
Subtracting 416 from 449 leaves us with 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 52

Advancing to step 8:
52 goes into 332 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 845986.0
If we subtract 312 from 332, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
52 goes into 200 3 times with a remainder of 44.
The next digit of our result is 3. 
Result so far: 845986.3
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
If we divide 440 by 52, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 845986.38
The remainder is 24 after subtracting 416 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
When dividing 240 by 52, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 845986.384
If we subtract 208 from 240, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
When dividing 320 by 52, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 845986.3846
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
80 divided by 52 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 845986.38461
If we take 52 away from 80, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
When dividing 280 by 52, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 845986.384615
Deduct 260 from 280 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
200 divided by 52 is 3 with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 845986.3846153
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 16:
The number 52 fits into 440 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 845986.38461538
If we subtract 416 from 440, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 845986.38461538, and the remainder is 2.4e-08.
